Cannot uninstall Exchange 2013 from Server with REFS file system

EX2013 SP1 installed fine on the 2012 R2 server with REFS, but now I need to remove it and reinstall. When I go to uninstall it, I get an error that "the specified installation directory must be located on a NTFS file system". I have tried
via control panel and command line.
I could avoid the uninstall if I could replace the Enterprise Edition license key with a standard key. the "Change License Key" option only allows you to go from standard to enterprise.
Any advice on either issues? (uninstall from REFS or change enterprise key to standard key)
According to the below TechNet article REFS is supported for an install, but maybe not an uninstall
http://technet.microsoft.com/en-us/library/ee832792(v=exchg.150).aspx

Hi,
1. I suggest romving previous Exchange server via ADSIEdit.
NOTE: It is better to try the steps with the assistance of a MS support. Do remember to backup the AD.
2. Then reformat the file system to NTFS.
3. Last, reinstall the new standard Exchange version.
Thanks

Cannot Uninstall Exchange 2003 from former SBS2003 server

Hi,
I have this problem uninstalling Exchange 2003 from a prior SBS2003 installation.
Started with SBS2003 with Exchange2003 on server1
Then added server2, with Exchange2003 Standard
Then transitioned succesfully Server1 from SBS2003 to Server2003 Standard with Exchange2003 standard.
Now I have added 3 Exchange2010 servers and migrated completely to Exchange2010.
Uninstallation of Exchange2003 Standard from Server2 went succesfully.
I cannot find a way to uninstall the last Exchange2003 Standard from Server1
In Control Panel add remove programs there's no option to enter SBS setup anymore.
When starting setup.exe from SBS CD2 (i386 directory) I'm asked for a Product Key but I have no valid key to enter. Tried SBS key, Transition key, nothing works.
When downloading an Exchange2003 SP2 installation exe I only have the option to upgrade the existing installation. No option to uninstall.
What is the way forward? I'm stuck right now.
Regards,
Joost

Hello,
If you don't uninstall exchange 2003 in Control Panel add/remove programs, you may need to uninstall it by ADSIEDIT. Do not remove this Administrative Group unless you’re absolutely sure there’s
no object in Active Directory referencing this Administrative Group in the ExchangeLegacyDN attribute.

I am trying to install Exchange 2013 and we already have Exchange 2007 in our production environment.
Running the command get-exchangeserver |fl give the following. It shows IsCleintAccessServer : False, I am pretty sure I did select both the roles at the time of installation.

I can see all the virtual folders in IIS and while trying to access the ecp page using https://localhost:444/ecp?exchclientver=15, it says "Sorry! Access Denied".
Get-ecpvirtualdirectory gives no output.
If I try to uninstall I get the following error.

I would like to uninstall this server and do a fresh install. Tried recover option too, still facing same problem.
HELP!!!

Hi,
I suggest re-install CAS role for test whether it works.
If not, please uninstall the MBX role as what you want. I suggest make a full backup if there is any data in the Exchange server, then remove the mailbox database.
Found an article for your reference:
Cannot remove mailbox database
http://technet.microsoft.com/en-us/library/ms.exch.setupreadiness.unwillingtoremovemailboxdatabase(v=exchg.150).aspx
After uninstall the Exchange server, I suggest double check whether there is anything leave in AD via ADSIEdit tool. Then re-install Exchange server.
Thanks

Cannot install Exchange 2013 on Server 2012 R2

I receive the following error when attempting to install Exchange Server 2013 on the same machine running Windows Server 2012 R2 Essentials:
"An unsupported operating system was detected. Exchange Server 2013 Client Access and Mailbox Server roles support Windows Server 2008 R2 SP1 or later and Windows Server 2012"
SP1 for Exchange Server 2013 was released but I'm not sure how to integrate it or whether or not I even need to. Please let me know if there is a fix or workaround.
Thank you.

This is correct, Essentials is not supported to host Exchange 2013
You need to install Exchange on supported OS:

Refresh to New Server with different file system

Dear Gurus,
We are having our Production DB,Test and RMAN in 10.2.0.3. We are trying to refresh TEST database with production db with last months backups and I've few queries.
Below is the filesystems:
Prod: /u99 for backup
Test: /ttu/t99 for backup
Datafiles locations are different and I can use either "SET NEWNAME" or "DB_FILENAME_CONVERT".
My production uses catalog database RMAN.
How can we duplicate test db with production (having catalog) with different backup locations on both systems. We don't have permissions to create similar directory structure on test machine.
With this I only left with restoring the production db on test server and then renaming the database. But, I want to know, if there's any possibility with RMAN directly to refresh TEST db.
Please help me.
Regards,
Kumar

If you want copy database to different OS, the n you must use transportable tablespaces
see more : http://docs.oracle.com/cd/B19306_01/backup.102/b14191/ontbltrn.htm
if you want copy database to same OS, then you can use backup based - DUPLICATE command or disaster recovery with is you shall use RESTORE database with SET NEWNAME option.

How to remove / uninstall Exchange 2013 Microsoft Document.

Dear Support,
We have just finished a complete migration from Exchange 2013 to Office 365 Exchange Plan.
Our on-premise Exchange 2013 has been powered off for the last three weeks and we are now ready to proceed and remove and delete Exchange 2013 from our Windows 2012r2 domain.
Our domain is as follows :
Windows 2012r2 ( 2 x Domain Controllers)
Exchange 2013 ( 1 Server with around 80 mailboxes and some PF)
I cant seem to find an official Microsoft guide on "How to remove Exchange 2013 completely"
Once again my exchange server still has all of its database etc, we have simply power it off and are ready to uninstall it, I just a MS Guide to follow, I've seen loads of various posts but no official instructions.
Cheers
Roger

Hi Roger,
Thank you for your question.
By you state, Exchange 2013 has been powered off for the last three weeks, so we think message flow and PF have no problem on office 365. We could refer to the following link to remove Exchange 2013:
https://technet.microsoft.com/en-us/library/ee332361(v=exchg.141).aspx
Notice: This is a link which is about Exchange 2010, but it also apply to Exchange 2013.
If there are any questions regarding this issue, please be free to let me know.
Best Regard,
Jim

Can't uninstall Exchange 2013 - (Distribution groups)

I need help uninstalling Exchange 2013. The uninstaller fails with these 2 errors:
This computer is responsible for expanding the membership of 1 distribution groups. These groups must be reassigned to another server before Setup can continue.
This computer is responsible for expanding the membership of 1 dynamic distribution groups. These groups must be reassigned to another server before Setup can continue.
I've gone so far as to disabling all distribution groups which removes its email properties and the uninstaller still fails.
This is what happens in the eventlog:
System.Management.Automation.ParseException: At line:1 char:67
+ Get-DynamicDistributionGroup | where {$_.ExpansionServer -eq '/o='s-Hertogenbosc ...
+ ~~~~~~~~~~~~~
Unexpected token 's-Hertogenbosch/ou=Exchange' in expression or statement.
At line:1 char:175
+ ... s/cn=CADEXCDB13'}
+ ~~
The string is missing the terminator: '.
At line:1 char:38
+ Get-DynamicDistributionGroup | where {$_.ExpansionServer -eq '/o='s-Hertogenbosc ...
+ ~
Missing closing '}' in statement block.
at System.Management.Automation.PowerShell.EndInvoke(IAsyncResult asyncResult)
at Microsoft.Exchange.Configuration.MonadDataProvider.MonadPipelineProxy.ClosePipeline(MonadAsyncResult asyncResult)
] [ParentValue:"<NULL>"] [Thread:11] [Duration:00:00:00.0156248]
I'm sure what happens here is the powershell commands looking at the distribution groups fail, because of our city name ('s-Hertogenbosch). Because of the apostrophe, the parameter is not passed successfully of this legacyExchangeDN. As this check fails,
I believe the readiness check fails on these steps.
This legacy administrative group name is still left from a 2003 -> 2010 -> 2013 migration.
I've opened a Microsoft support request for this last week, but I thought someone might have dealt with this? I want to do a clean uninstall if possible.

After I removed the distribution groups, I did restart the server.
The problem is the the powershell script to check for existing distribution groups use a single quote to pass the server name to it. The server name contains a single quote itself so the parameter is not passed successfully. If the powershell script
used a double quote it would pass the parameter correctly.
This works:
Get-DistributionGroup | where ExpansionServer -eq "/o='s-Hertogenbosch/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Configuration/cn=Servers/cn=CADEXCDB13"
This does not work:
Get-DistributionGroup | where ExpansionServer -eq '/o='s-Hertogenbosch/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Configuration/cn=Servers/cn=CADEXCDB13'
Do you see the difference? (Parameter is passed in a single or double quotation)

I was installing Exchange 2013 on Server 2012. The server is not a DC, but is a member of a domain with a 2008 R2 functional level, and I was logged in as a domain admin. There has never been an Exchange instance on this domain. I got past
the prerequisite checks, and the installer showed 15 steps, so I walked away. When I came back, I saw this:

Hi Deepak,
From the error description, I would like to clarify the following things:
1. Please ensure that IPv6 on the network adaptor is turned on.
2. Please check if the account that you used to install Exchange has necessary permissions to perform the installation.
3. Make sure that DNS is configured correctly.
Hope my clarification is helpful.
If there are any problems, please feel free to let me know.

'Cannot obtain error message from server' when trying to use ODBC

Post Author: Grant C
CA Forum: Data Connectivity and SQL
Hi, I'm developing some reports using Crystal XI on my local PC, using an Oracle 10i back end on a separate server. The SQL for the report is in a method in an oracle package.
When I set the datasource location, selecting 'Oracle Server' then entering the details works fine, and the report runs. However, when I try to use an ODBC connection I get the following error:
Database Connection Error: 'Cannot obtain error message from server.'
The ODBC link is set up as a System DSN, which works fine when I test it. I think I need to use ODBC as some of the reports (which I inherited) seem to fail when run on the Crystal Server, and it seeme to be the ones set up with ODBC which work.
Any thoughts? Thanks.

Hi Mars-
It sounds like your NI-DAQ installation may have become corrupted. I would suggest uninstalling and reinstalling the DAQmx 7.4 driver to correct this problem and ensure that you're up to date. This download is available here: NI-DAQ 7.4
If the problem persists you may want to uninstall and reinstall LabVIEW and then NI-DAQ in that order. The error message will usually give an indication as to which VI the error occurred in. Please let us know which VI is failing if you're unable to avoid the error with these suggestions.
Have a good day-

Support for TLS 1.2 over Exchange 2013 on Server 2012?

Greetings,
We're trying to roll out TLS 1.2 in our test environment and can't seem to get Exchange to work with the protocol.
We've been using this method to enable TLS 1.2 (and disable the other protocols - TLS1.0, SSL2.0, SSL3.0, PCT1.0): http://www.adminhorror.com/2011/10/enable-tls-11-and-tls-12-on-windows_1853.html
We originally tried using Exchange 2010 on 2008 R2, but then I ran across this article saying that it is not supported: http://support.microsoft.com/kb/2709167/en-us
We've since tried to set it up with Exchange 2013 on Server 2012. Still no luck. The only time Exchange wants to work is when TLS1.0 is enabled.
I suspect that TLS1.1 and TLS 1.2 are also not supported on Exchange 2013, or that I'm changing the wrong registry keys, but I wanted to find confirmation. I've searched extensively and can't find any documentation leading me to believe one way or the other
if it's supported.
Any help or insight would be greatly appreciated. Thanks!

hi All,
Even i have tried enabling TLS 1.2 on Exchange 2013 from registry. i followed the below article.

When i check OWA in chrome and check the connection information it says "The connection uses TLS 1.2.
However when i run the below command to check for TLS 1.2 i get the following O/P.

New Exchange 2013 CAS server in existing Exchange 2007 Organization

Dear Friends,
We have exchange 2007 SP3 with CU13 installed with single copy cluster for database and 1 OWA server for CAS/HT. We will migrate from current to Exchange 2013SP1. As we want to have HA, we have installed 2 new Exchange 2013 SP1 CAS server on widnows 2012
R2 after preparing our organisation for Exchange 2013. The setup went smooth without any error and successfully installed CAS with management tools. After installation it ask to reboot the server which we did. Now after reboot, we are not able to run Exchange
Management Sell. It never connects to the new server. In our old 2007 EMS also doesn't list any exchange 2013 server. We are also not able to connect to new CAS servers with below URL:
https://servername/ecp/?ExchClientVer=15
Its says site under maintenance. Please advise what to check. We were thinking of deploying CAS 1st and make it co-exist with Exchange 2007 before deploying Exchange 2013 mailbox server which will be setup in DAG. What are we doing wrong.
Thanks in advance!!

If you have only the 2013 CAS installed and not the mailbox role, then nothing will really work. Remember, in 2013, the mailbox role does all the work, the CAS is simply a proxy for the most part.

Exchange 2013 CAS server connection to Exchange 2010 Mailbox server

Hi Guys,
I have a quick question i am planning to upgrade my infra from Exchange 2010 to Exchange 2013 and i have come across a small question, my infra looks likes below
3 Exchange server (CAS+ HT + MBX roles) Exchange 2010
1 Exchange server MBX role For journlaing Exchange 2010
1 CAS for internet owa access Exchange 2010
Now i will be installing exchange 2013 CAS on 2 box and MBX on 3 box
will decomm the 3 exchange box which has (CAS+ HT + MBX roles) and 1 CAS which we use for owa access.
will keep the Journaling server as it is will not be decomming it as of now.
My question is is will i be able to connect to the journaling mailbox's which are hosted on exchange 2010 journaling server without actually having any 2010 cas server, will exchange 2013 cas directly help me to connect to the journal mailbox or would i need
to add CAS role on Exchange 2010 journaling server and enable outlook anywhere configure the directories with the url's to make it working.
Please suggest on the same.

Hi TheLearner,
Thank you for your question.
Exchange 2013 didn’t connect to the journal mailbox directly when we access it by outlook/OWA. The journal mailbox will connect the former Exchange 2010 CAS. Or we could migrate Journaling mailbox to Exchange 2013. Because Exchange 2010 could communicate
with Exchange 2010 by RPC, but Exchange 2013 could communicate with Exchange 2013 by HTTPS.
If there are any questions regarding this issue, please be free to let me know.
Best Regard,
Jim

Exchange 2013 OWA server accessing mailboxes on Exchange 2007

Hi All-
I just completed the installation of Exchange 2013, co-existing with Exchange 2007. I have 2013 CU1 and 2007 SP3 RU10. The issue I have is that I cannot access mailboxes existing in the 2007 mailbox servers through my 2013 OWA server. Is
there some advanced configuration that I need to do, on either 2007 or 2013? The documentation I have read seems to indicated that I should be able to use OWA 2013 to access 2007 mailbox.
TIA,
Chris
